EXPERIMENT 1: INFLUENCE OF THE EFFICACY OF A PROBIOTICS COMPLEX CONTAINING BACILLUS SUBTILIS AND PICHIA FARINOSA, ON THE GROWTH PERFORMANCE AND FECAL MICROBIOTA OF FINISHING PIGS AND BROILER CHICKEN
This study was to evaluate the efficacy of probiotics complex containing Bacillus subtilis and Pichia farinose on growth performance and fecal microbial in finishing pigs and broiler chicken. Two experiments were conducted with three dietary treatments groups: (i) basal diet (CON), (ii) CON + 0.1% probiotics complex (TRT1), (iii) CON + 0.2% probiotics complex (TRT2). In Experiment 1, 120 finish pigs [(Landrace × Yorkshire) × Duroc; 52.61 ± 2.37kg] were randomly allotted into three treatments for 70 days trial to evaluate the growth performance and fecal microbiota counts in finishing pigs. Each treatment consisted of 8 replicate pens with 5 pigs per pen. In Experiment 2, 576 one-day-old mixed-sex Ross 308 broilers were fed experimental diets for 35 d. The birds were assigned to 3 groups with 16 replicates each based on similar body weight (BW) (42 ± 0.08 g). In Experiment 1, the average daily gain, and fecal Lactobacillus counts of TRT2 were increased (P < 0.05) compared with CON treatment. The result showed that 0.2% complex probiotic was more effective than 0.1%. In Experiment 2, The feed conversion ratio (FCR) was lower (P < 0.05) in broilers fed 0.2% and 0.1% probiotics complex supplemented diets than those fed with CON diet during d 1-7; in addition, broilers fed with 0.2% probiotics complex diet had lower (P < 0.05) FCR than broilers fed CON diet during d 21-35 and overall period. Supplementation of 0.2% probiotics complex diet had greater (P < 0.05) body weight gain than CON diet during overall period. In conclusion, the supplementation of probiotics complex in finishing pigs and broilers diet has shown a beneficial effect in growth performance, and increase fecal Lactobacillus counts and a dose effect was also seen in measured parameters.
EXPERIMENT 2: EFFECT OF PROBIOTICS COMPLEX SUPPLEMENTATION IN LOW NUTRIENT DENSITY DIET ON GROWTH PERFORMANCE, NUTRIENT DIGESTIBILITY, FAECAL MICROBIAL, AND FAECAL NOXIOUS GAS EMISSION IN GROWING PIGS
The objective of the present study was to evaluate the effect of supplementing low nutrient density diet of growing pigs with probiotics complex on growth performance, nutrient digestibility, faecal microbial, and faecal noxious gas emission. A total of 140 crossbred female and castrated male healthy growing pigs [(Yorkshire × Landrace) × Duroc, 54 days of age] with an average initial body weight (BW) of 24.39 ± 2.58 kg were used in a 42-day trial. All pigs were randomly allotted to 1 of 4 treatment diets based on initial BW and sex (7 replicate pens/treatment; 2 gilts, and 3 barrows/pen). Dietary treatments were: (i) HD, high nutrient density diet, (ii) LD, low nutrient density diet, (iii) T1, LD + 0.05% probiotics. (iv) T2, LD + 0.10% probiotics. At the end of the experiment BW, average daily gain (ADG), and gain: feed ratio (G: F) tended to be higher (P 0.05) in average daily feed intake (ADFI), backfat thickness, lean meat percentage, and apparent total tract digestibility (ATTD) of dry matter (DM), nitrogen (N), and energy among the treatments. The supplementation of probiotics complex to LD diet increased (P < 0.05) fecal Lactobacillus counts and reduced NH3 gas emission compared with the LD diet. In conclusion, the results of this study demonstrated the beneficial effects of the probiotics complex supplementation on growth performance, faecal Lactobacillus concentration, and faecal NH3 emission in LD diet suggesting.
EXPERIMENT 3: EVALUATION ON THE GROWTH PERFORMANCE, NUTRIENT DIGESTIBILITY, FAECAL MICROBIOTA, NOXIOUS GAS EMISSION, AND FAECAL SCORE ON WEANING PIGS SUPPLEMENT WITH AND WITHOUT PROBIOTICS COMPLEX SUPPLEMENTATION IN DIFFERENT LEVEL OF ZINC OXIDE
A total of 200 26-day-old crossbred weaning piglets [(Yorkshire × Landrace) × Duroc; 6.55 ± 0.62 kg] were used in a 6-week experiment to evaluate the effects of probiotics complex (SynerZymeF10) supplementation with high and low level of ZnO diets on the growth performance, nutrient digestibility, faecal microbiota, noxious gas emission, and faecal score in weaning pigs. Pigs were randomly allotted in a 2 × 2 factorial arrangement and they were supplemented with two concentration level of ZnO with 3000 ppm and 300 ppm and probiotics complex supplementation with 0 and 0.1%. There were ten replicate pens per treatment with five pigs per pen (two gilts and three barrows). Pig fed diets with 3000 ppm ZnO had a higher BW during the overall period and ADG during d 8-21, d 22-42, and overall period than pigs receiving 300 ppm ZnO diets (P < 0.05), as well as an G: F was trend to increase on d 8-21and overall period (P < 0.1) and decreased tendency on faecal gas emission of methyl mercaptans and acetic acid concentration (P < 0.1). Dietary probiotics complex supplementation had decreased the E. coli count (P < 0.05) and tended to increase the Lactobacillus count (P 0.05). In conclusion, probiotic supplementation has reduced the fecal E. coli counts and tended to improve Lactobacillus counts. There were no interactive effects between ZnO and probiotic complex supplementation on all the measured parameters.
